nimotuzumab combined with concurrent chemoradiotherapy for locally advanced treatment esophageal cancer in old age

Conditions: Esophageal Carcinoma

Summary: the research subjects of this project are mainly aimed at patients with locally advanced esophageal cancer who cannot be treated surgically, in taixinsheng 3 months after the end of concurrent chemoradiotherapy, recist is pressed as based on physical examination and esophageal barium dialysis or esophageal contrast-enhanced ct criteria assessed short-term and long-term efficacy separately. by detecting the expression of egfr in patients with locally advanced esophageal cancer, the relationship between the efficacy of egfr monoclonal antibody therapy and the long-term prognosis of patients was evaluated. evaluation of safety, toxicity and side effects during treatment and in the near and long term.

it is expected that 45 patients will be enrolled, and patients who meet the enrollment criteria will undergo esophagoscopy, esophageal barium meal examination, chest contrast-enhanced ct, abdominal ultrasound, electrocardiogram, blood routine, whole body bone scan, liver and kidney function and other examinations before treatment, and esophageal ultrasound if necessary. patients who received esophageal ultrasound were staged by esophageal ultrasound results, and those without esophageal ultrasound were mainly staged according to the cervical chest and epigastric contrast ct and esophageal barium plates, and clinical staging was performed according to the 2002 ajcc staging standard. after the combination of taixinsheng and concurrent chemoradiotherapy, adverse reactions and efficacy evaluation were observed. the expected result is that the local control rate of egfr monoclonal antibody combined with chemoradiotherapy is improved in patients with locally advanced elderly esophageal squamous cell carcinoma, and there is no significant increase in adverse reactions, and serological indicators such as egfr can be used as prognostic indicators for esophageal malignancy and have certain guiding significance for treatment. egfr monoclonal antibody can be used in locally advanced elderly esophageal cancer patients who cannot tolerate chemotherapy, with good short-term efficacy and tolerable toxic side effects, which further provides reference value for clinical guidance.

Eligibility criteria:
inclusion criteria: 1. locally advanced senile esophageal cancer that cannot be treated surgicallyr (t3-4n0 or any n+); 2. the pathological type is esophageal squamous cell carcinoma; 3. immunohistochemistry showed medium and strong expression of egfr; 4. no signs of perforation, such as protruding spikes, niche shadow formation, twisted angles and mediastinal disorder; 5. karl fischer score (kps) ≥ 70, age ≥ 70 years old, can eat a semi-liquid diet; 6. no serious comorbidities, such as severe obstructive emphysema, hypertension, coronary heart disease, diabetes and psychiatric history, etc., and no other malignant tumors; 7. all patients had not received egfr-targeted therapy, immunotherapy, and chemoradiotherapy. exclusion criteria: -
